Hey folks, I'm having a bit of trouble understanding the two different ways of

getting

an existing resource, for example: • one can use the function:

aws.service.get_resource()

• or the static method:

aws.service.Resource.get()

E.g., to get an existing S3 bucket, one can do:

aws.s3.get_bucket(bucket='myBucket')

or

aws.s3.Bucket.get(resource_name='myBucket', id=123456)

. What's the difference between the 2? Is there any caveat of using one over the other that I'm not aware of?

Yes there is a difference

resouce.get

get_resource()

- https://www.pulumi.com/docs/intro/concepts/resources/functions/

thanks @great-sunset-355, I'll check those links out!

in general, I tend to avoid

resource.get

because in past it had some weird consequences (I do not remember now, sorry) and use

get_resource

or rather

get_resource_output

which works as expected

is there any advantage of using

get_resource_output

over

get_resource

? The whole input / output thing is still a bit esoteric to me. I find that whenever I need a resource value (e.g. the ID), most times I have to

apply()

to use it.

The get_resource functions return (your language's version of) a promise, which you have to handle in the normal way. The get_resource_output functions wrap those promises in outputs. The primary benefit of this is member lifting: you can pass a value inside the output object into a Pulumi resource constructor without waiting for the promise to resolve.
